BOSTON - The Boston Marathon bombing suspect police had been hunting since before dawn Friday in the town of Watertown, Mass. has been taken into custody, alive but seriously injured.

He was taken away in an ambulance, his exact wounds unknown.

Just before 9 p.m ET Boston police tweeted, "CAPTURED!!! The hunt is over. The search is done. The terror is over. And justice has won. Suspect in custody."

There was a round of applause from the residents as police officers announced Dzhokhar Tsarnaev's arrest to the crowd gathered in the area. Officers were seen giving each other high-fives and fist bumps.

"We're exhausted folks, but we have a victory here tonight," Massachusetts State Police Superintendent Timothy Alben said at a news conference around 9:30 ET.

Boston Police Commissioner Ed Davis said police officers narrowed in on Dzhokhar's hideout when a man walked outside and saw blood on a boat in his back yard. The man opened the tarp covering the boat and saw the suspect inside covered in blood, Davis said.

Police surrounded the home at 67 Franklin Street around 7 p.m ET and unleashed a barrage of gunshots followed by flash bang grenades.

"Over the course of the next hour or so we exchanged gunfire," Davis said.

"Ultimately, the hostage rescue team of the FBI made entry into the boat and took the suspect alive," Davis said. "We always want to take somebody alive, so we can find out what happened, why it happened."

Police negotiators did try to talk him out of the boat but "from what I can understand he was not communicative," Davis said.

The 19-year-old Dzhokhar, of Russia, was believed to have been armed with assault rifles and an assortment of other weapons, including bombs, according to ABC News. Officials were concerned he might try to take hostages.

Dzhokhar had been on the run since about 1 a.m. ET Friday when his older brother, Tamerlan Tsarnaev, was killed in a shootout with police in Watertown after a wild car chase, Boston police said.

During the early-morning shootout, the brothers detonated one pressure-cooker bomb -- like the two explosives used in the deadly Boston Marathon attack -- and also set off several pipe bombs, police said during a Friday afternoon news conference.

Investigators also found several undetonated pipe bombs at the scene.

Police thought that Dzhokhar somehow escaped, despite a massive law enforcement door-to-door search of a 20-block area in Watertown.

"My message to the suspect is to give himself up," Massachusetts State Police Superintendent Timothy Alben said Friday at 6 p.m. EST announcing that the "shelter in place" order for Boston-area residents was lifted.

An hour later, a round gunshots rang out, signaling the end of the police search for Dzhokhar.

"The citizens of the city of Boston and this area can be confident the threat is removed," Davis said.

"It seems like many months since April 15," said FBI Special Agent Rick DesLauriers. "This was truly an absolutely intense investigation."

He commended the work of local law enforcement officers.

"As a result of that, justice is being served for the victims of these terrible crimes,"DesLauriers said.

"We've closed an important chapter in this tragedy," President Barack Obama said in a brief press conference at the White House Friday night. "Whatever thought they could achieve, they've already failed."

The entire city of Boston was nearly paralyzed by the search for person the FBI had dubbed "Suspect 2."

Just after the shootout with the two brothers around 2:30 ET, police warned residents of Watertown, Mass., to stay indoors and not answer the door unless instructed by uniformed police officers. That shelter-in-place request was extended to the 1 million people in the entire Boston area at 8 a.m. ET.

For most of the day, Boston's streets were virtually empty. AMTRAK service between Boston and New York was suspended, as was all mass transit. Businesses were asked not to open. People waiting at bus and subway stops were told to go home. The Red Sox and Bruins postponed their Friday games.

-- Overnight events --

Authorities suspected the chaotic night of violence began with the report of a carjacking at a 7-Eleven in Cambridge Thursday night.

Then, at about 10:20 p.m. ET, a Massachusetts Institute of Technology campus police officer was found after he was repeatedly shot in his patrol car. The officer, later identified by the university as Sean Collier, 26, was pronounced dead at a hospital and police said two male suspects were believed to be responsible.

As dozens of local and state police spread across Cambridge searching for the killers, two men reportedly left the area in the carjacked black Mercedes SUV.

The carjacked driver was kept inside that SUV for about a half hour before being released at a gas station, the Middlesex District Attorney said.

State Police spokesman Dave Procopio said police realized they were dealing with the bombing suspects based on what the two men told a carjacking victim during their getaway attempt.

Somewhere in the Watertown area, the carjacked SUV was spotted and a police pursuit began.

Gunfire was exchanged and police said explosives were thrown from the SUV during the firefight.

Watertown residents reported the sounds of explosions and automatic gunfire early Friday morning. Some tweeted photos of bullet holes in their homes.

During that shootout, a transit police officer was shot. Richard H. Donohue, Jr., 33, has worked as a officer with the Massachusetts Bay Transportation Authority for three years. He was last listed in critical condition at a Boston area hospital. Collier and Donohue, Jr. are friends, having attended the police academy together in 2010.

The man believed to be Suspect 1, Tamerlan Tsarnaev, was also shot, and later died at Beth Israel Deaconess hospital. Doctors there described him as arriving in a state of "dramatic arrest" and having a combination of blast and gunshot wounds.

Dzhokhar escaped the firefight and eluded the search that lasted throughout the day.

"He managed to elude us by being just slightly outside of the perimeter that we set up," Boston's police commissioner said.

Boston police initially said Dzhokhar may be driving a green 1999 Honda sedan with Massachusetts license plate 116-GC7. However, by 3:45 p.m. ET, Boston police tweeted that they had found the car and were no longer looking for it.

Earlier, Boston police recovered an abandoned gray Honda CRV believed to be the place where the brothers spent the night. It was empty. It was seized and processed for evidence.

The bombings at the Boston Marathon finish line on Monday killed three people and wounded more than 180 others, tearing off limbs in a spray of shrapnel and instantly raising the specter of another terrorist attack on U.S. soil.

Investigators in the Boston case have shed no light on the motive for the bombing and have said it is unclear whether it was the work of domestic or international terrorists or someone else entirely with an unknown agenda.
